B ultrasound examination
Usually at about 4 months of pregnancy, the sex of the fetus can be clearly identified through B-ultrasound examination. However, the results may be biased. Whether it is a boy or a girl, maternal and child health and safety are the first.
Forecast method of folk circulation
There are some interesting methods circulating among the people to predict fetal sex. For example, by analyzing the size and shape of gestational sac, the difference between biparietal diameter and femur length, the change of pregnant women's taste, the shape of belly and the speed of fetal heart rate, some people try to find clues to give birth to boys and girls. But please remember that these methods are based on experience and observation, and there is no scientific basis.
Keep a relaxed and cheerful mood.
During pregnancy, it is most important to keep a relaxed and happy mood, have regular checkups and develop healthy living habits. The real answer is to wait for the natural announcement of the delivery time.
